A commuter train en route to Washington, D.C., derailed during early
Thursday's rush hour, injuring five people, police and rail officials said.
Three cars and the engine went off the tracks in Prince William County,
Virginia, and three passengers and an employee of Virginia's Railway Express
were injured, CNN reported.
The four injured were taken to a hospital.
A fifth person was taken from the crash in a life-support unit, news reports
said.
About 500 people were onboard the train, said Mark Roeber, a company
spokesman.
Some 15 Amtrak trains were delayed or canceled, and about 3,000 passengers
were affected, Amtrak spokesman Cliff Black said.
The cause of the accident was not immediately known, and officials from the
National Transportation Safety Board and the Federal Railroad Administration
were at the site to find out what had caused the derailment.
